摘要:
Disclosed is a melt-blended thermoplastic composition including: A) a polyamide composition including a) 55 to 90 weight percent semi-crystalline semi-aromatic copolyamide; wherein the semi-aromatic copolyamide has a DMA tan delta peak value of greater than or equal to 0.23; and heat of fusion of at least 20 J/g and b) 10 to 45 weight percent aliphatic homopolyamide; wherein the aliphatic homopolyamide has a DMA tan delta peak value of less than or equal to 0.21; and heat of fusion of at least 30 J/g; B) 0 to 45 weight percent polymeric toughener; C) 0 to 20 weight percent plasticizer; and D) 0 to 45 weight percent reinforcing agent; wherein said melt-blend composition has a glass transition and has a tan delta peak (E″/E′) value of 0.21 or lower at said glass transition. Further disclosed herein is a method for providing the melt-blended thermoplastic composition.
